Power Technologies Energy Data Book - Fourth Edition

Abstract

The main purpose of the data book is to compile, in one central document, a comprehensive set of data about power technologies from diverse sources. The need for policy makers and analysts to be well-informed about power technologies suggests the need for a publication that includes a diverse, yet focused, set of data about power technologies. New for this fourth edition of the PTEDB is Chapter 13, which features Geographic Information System (GIS) maps. One set of maps shows the natural resource (biomass, geothermal, solar, and wind) overlaid with the national transmission grid and the major electricity load centers. The other set of maps shows the current installed capacity (biomass, geothermal, concentrating solar power, and wind), as well as a bar chart indicating the historic trend of generating capacity for the state.

Quantifying the hurricane risk to offshore wind turbines

“…Installing lead-acid batteries to allow a turbine to yaw without external power would add $30,000-$40,000 (2010 prices) to the price of a turbine and 1,400-2,400 kg to its weight, assuming 6 h of backup power for yaw motors that draw 12 kW of power (27). The yaw rate of the turbine we model is 0.3°per second.…”

Fuel Cell Power Model Version 2: Startup Guide, System Designs, and Case Studies. Modeling Electricity, Heat, and Hydrogen Generation from Fuel Cell-Based Distributed Energy Systems

“…The data were normalized to 2005 dollars and analyzed over a period from 1993 to 2008. Figure 52 shows cost data collected from a number of sources [4,6,7,[13][14][15][16][17][18]. An average installation factor of 1.15 was found between uninstalled and installed plant costs.…”

Growing Complexities: A Cross-Sector Review of U.S. Biofuels Policies and Their Interactions

“…Biomass gasification, where biomass is converted to a synthetic gas which is then used for electricity generation, potentially could provide even higher efficiencies (greater than 40 percent). While gasification technology exists, it is not yet cost effective for widespread commercialization (Aabakken 2006).…”

“…The overwhelming majority of these (95 percent) are wood-fired facilities that use forestry residues to generate on-site power for pulp and paper industry uses. 33 Most of these are small direct-combustion facilities that use limited-residue resources, meaning 33 Two-thirds use the power and heat for on-site uses only, while others have the ability to provide power back to the grid (Aabakken 2006). they burn wood without more efficient gasification technology.…”

“…they burn wood without more efficient gasification technology. As of 2006, utility and industrial biomass represented 75 percent of non-hydroelectric renewable electricity generation with wind, solar, and geothermal generation making up the remaining 25 percent (Aabakken 2006). If biomass electricity generation were to increase, the short-term uses for biomass at large scales would most likely occur through co-firing in existing coal plants.…”
